10 Claims.

The invention relates to sinks, wash basins and the like formed fromsheet or plate metal and preferably covered by a protective coating,such as an enamel coating. More particularly, the invention relates tosuch products in which a fluid receiving bowl, together in some caseswith one or more drain boards, terminates in a rolled rim and acomparatively high splash-back lying in a plane substantially at rightangles to the plane of the top of the rolled rim, and are all formed inand from a single piece or blank of sheet or plate metal.

Enamel coated cast metal sinks and the like have been made, but thesame, particularly in large sizes, are very heavy and require two orthree men to handle the same in installing such sinks; and frequentlythe larger sizes require legs to prevent sagging or to prevent unduestrain upon the wall where they are installed.

Sheet metal enamel coated sinks have heretofore been made in which thebowl portion and a high splash-back therefor are either bolted or weldedtogether. However, the appearance of such sinks is objectionable eitherbecause of the exposure of bolt heads, or because of the difficulty ofmaking a satisfactorily welded joint without having the same more orless noticeable after being enameled.

Sheet metal sinks have also been made in which the bowl is surrounded bya rolled rim and is provided with a high upstanding splash-back, allformed from a single sheet of metal. However, such sinks have alwaysbeen provided with notches or openings at the place where the ends ofthe rolled rim meetthe splash-back, in order that the splash-back couldbe moved to an upright position by a bending operation, after which thecut edges of the slits or notches at the ends of the rolled rim, arewelded together where the rolled rim meets the splash-back.

Such notching, slitting and welding operations are not only expensive,but the welded joint, in having a curved and recessed contour where therolled rim ends and the spash-back meet, are always more or lessnoticeable and are difiicult to cover with a satisfactory enamel coatinghaving the same properties as the enamel coating on the remainder of thesink.

Moreover, when extremely long sinks are made, as when they are providedwith a drain board at one or both sides of the fluid receiving bowl, orwhen large fluid receiving bowls are provided, the plane of the uprightsplash-back has always been located substantially continuous with theplane of the rear fluid receiving bowl wall; and it is difiicult tomaintain a truly plane surface for the splash-back when subjecting thesink to heat for enameling the same, since the unequal strains imposedupon the splash-back during the forming operations may cause a slightwarpage or 5 Weaving of the splash-back when the same is heated in theenamellingfurnace.

Accordingly, it is-an object of the present invention to' provide animproved construction for sinks, wash basins and the like, whichovercomes the difiiculties which have resulted in prior sinkconstruction.

Furthermore, it is an object of the present invention to provide a sinkand the like, in which a fluid receiving bowl, together in some caseswith one or more drain boards, terminates in a rolled rim and in a;comparatively high splashback, and are all formed in and from a singlepiece or blank of sheet or plate metal without performing any notchingand/or subsequent o welding operations at the place where the rolled rimends merge with the splash-back.

It is likewise an object of the present invention to provide astiffening ledge at the top rear edge of the bowl of such a sink formedfrom a single 25 piece or blank of sheet or plate metal, which stiifensthe splash-back, and enables the splashback to be maintained in properposition without warping, weaving and the like when the sink issubjected to heat for carrying out an enamelling operation.

A further object of the present invention is to provide, in such sinkconstructions, a fluid receiving bowl having straight side walls, thatis with the bottom thereof just as large as the top, to provide amaximum capacity for the fluid receiving bowl.

It is likewise an object of the present invention to provide sinks ofsuch improved character, which may be readily coated with a preferably40 acid resisting enamel coating of the highest quality, so that theresulting coating is absolutely uniform in appearance andcharacteristics throughout, and which enamel coating is not weakened atany of the working surfaces of the sink due to 45 previous operations informing the sink prior to being enameled.

Amd finally, it is an object of the present invention to provide sinksincorporating the above described desiderata, which are very light inweight by being formed from sheet or plate metal, which are formed froma single blank of metal, and which are inexpensive to manufacture andhave a pleasing and attractive appearance.

These and other objects may be obtained by the constructions,arrangements, combinations, elements and formations, hereinafterdescribed in detail and claimed, preferred embodiments of which areshown in the accompanying drawing, which may be stated in general termsas including in a sheet metal'sink having a fluid receiving bowlpreferably with substantially upright side walls, and in some caseshaving one or more adjacent drain boards, the bowl and drain boardsterminating in a rolled rim and in an upright splash-back, all formedintegrally from a single sheet of metal; a preferably laterallycontinuous stiffening ledge preferably substantially S-shaped in crosssection formed between and merging into the bowl and splash-back toprovide an offset thereat, and in case drain boards are providedadjacent to the fluid receiving bowl, a portion of said ledge extendingbetween and merging into the drain boards and splash-back; the rolledrim being preferably continuous and surrounding the front and sides ofsaid bowl and .drain boards if used, the ends-of the rolled rimterminating at and merging into said splash-back, the places of mergerbetween the ends of the rolled rim being seamless, and the line ofintersection between the ledge and splash-back lying in the plane of theupper portion of the rolled rim.

' Referring to Figs. 1 and 5 to 9, inclusive, the

improved sink shown therein may include a fluid receiving bowl l0,having a bottom wall ll provided with a drain opening 12, and havingsubstantially upright or vertical walls, preferably substantiallyrectangular in cross section and ineluding a front wall l3, a rear wall14 and side walls IS, with preferably rounded corner walls l6therebetween. I

A drain board I! preferably provided with a multiplicity of parallelgrooves 18 set closely together, is preferably located adjacent to thefluid receiving bowl III, and the drain board I! preferably slopesslightly downward toward the bowl l0 as best shown in Fig. 8.

The bowl Ill and drain board I! preferably terminate in a preferablycontinuous rolled or preferably lying in an upright plane.

For the purposes of the present invention, the fluid receiving bowl III,the drain board l1, the rolled\pim l9 and the splash-back 20 are allformed integrally from a single sheet of metal; and may be preferablymade in accordance with the method set forth in my copending applicationentitled Process of making sinks, wash basins and the like, filedDecember 7, 1932, Serial No. 646,207, matured as Patent No. 1,916,910,dated July 4,

The outer portion of the rolled rim l9 may be preferably integrallyextended downward to form a long skirt 2| surrounding the fluidreceiving bowl in and drain board 11, as best shown in Figs. 1 and 6; orthe rolled rim l9 may terminate in a short skirt 2|a, as shown in Fig.3.

The ends or end portions 22 of the rolled ri l9 terminate at and mergeinto the splashback at 23; and a stiffening preferably continuous,ledge, generally indicated at 24, is formed between and merges into therear bowl wall I4, the drain board l1 and the splash-back 20." Thepresent invention involves particularly the improved construction of thesink at the places 23 and of the ledge 24.

The provision of the stiflening ledge 24, which is preferably parallelwith the rear bowl wall 14, offsets the plane of the bowl wall I4 fromthe plane of the splash-back 20 and thereby provides an offset at theplace where the ledge 24 merges'into the bowl and splash-back; and theledge 24 is preferably substantially S-shaped in cross section, andslopes generally rearwardly upwardly from the bowl to the splash-back,as best shown in Fig. 9, and may comprise'a curved portion 24a merginginto the bowl wall l4, and a flattened portion 24b, which merges into orintersects with the splash-back along a line 25, which line extendsbetween the places 23 and lies in the plane of the upper portion of therolled rim, as best shown in Figs. 6 to 9, inclusive.

As stated, the splash-back projects upwards from the rear of the fluidreceiving bowl l0 and since the intersection of the same with the ledgeportion 24b is the line 25, which line also passes through the places23, the splash-back 20 may be originally formed horizontal in aone-piece sheet blank along with the bowl I0 and rolled rim l9,

. and may thereafter be bent to the upright position shown, along theline 25, without having to notch the sheet blank around the places 23.The

places 23, where the ends of the rolled rim l9 passes through the line25, so that a fluid dropping to the drain boardwill flow along the sameinto the fluid receiving bowl in the usual manner.

The location of the ledge 24 and its substantially s-shape, togetherwith the offsetting of the splash-back 20 from the rear wall l4 of thebowl l0 materially stiflens the sink and the splash-back 20 so that thecorrect location of the splash-back may be maintained in a verticalplanewithout warping or weaving out of true when the sink is subjectedto heating in an enamel furnace for providing a preferably acidresisting vitreous enamel coating thereon.

LikewiseJihe fact that the places 2: where the ends of the rolled rim llmerge with the splashback 20 are seamless and need not be welded,enables the improved sinks to be inexpensively made and enables auniform enamel coating to be provided on the sink especially at theplaces 23.

Thus, the-present'improvements provide a very light weight sink formedfrom a single blank of metal which is inexpensive to manufacture, has

,a pleasing and attractive appearance, and is very strong in use.

The construction'shown in Fig. 2, is identical in all respects with thatshown in Fig. 1, excepting only that a left-hand drain board Ha isprovided, similar in all respects to the right-hand drain board l1; andthe splash back 20b'extends in back of the fluid receiving bowl and bothdrain boards I? and Fla.

The construction shown in Fig. 3, is similar to or identical with theconstruction shown in Fig. 1 in all respects excepting only that therolled rim i9 terminates in a short skirt 2 la.

The construction shown in Fig. 4, is the same as that shown in Fig.3,excepting only that the drain board is omitted and the splash-back 20ais shortened by the omission, of the drain board.

In the constructions shown in Figs. 2, 3 and 4 the ledge formation andthe seamless merger of the roll ends with the splash back is the same asthat shown in the remaining figures of the drawing.

In the foregoing description, certain terms have been utilized forbrevity, clearness and understanding; but no unnecessary limitations areto be implied therefrom or from the use of such words in the claims; andsuch terms are intended to be broadly construed, as follows:---

The word sink used herein and in the claims is intended to includesinks, wash basins, wash bowls and the like; the word sheet metal" isintended to include sheet and plate metal of the desired or necessarygauge; the words rolled rim are not intended to imply arcuately shapedrims since the rims may have any desired shape and may terminate witheither shallow or deep lar characteristics to enamel coatings, and thewords enamel coated are likewise intended to include materials such asstainless steel and the like, which may have characteristics in use forthe purposes of the present invention the same or similar to enamelcoated sheet metal.
